Benefits of technology
The patent text describes an optical splitter assembly used in fiber distribution hubs of fiber to the premises networks. The assembly includes a housing, an input adapter, an input fiber, an optical splitter element, a plurality of output fibers, and a first and second fanout elements. The assembly is designed to split the optical signal from the input fiber into multiple output fibers. The overall size of the assembly is relatively large and may be influenced by the size of the fiber loop. The technical effect of the invention is to provide a compact and efficient solution for optical splitter assemblies in fiber distribution hubs, reducing the size and complexity of the overall fiber distribution hub.

Embodiment Construction
[0006]Exemplary embodiments are described hereinafter with reference to the accompanying drawings, in which exemplary embodiments and examples are shown. Like numbers refer to like elements throughout.
[0007]Exemplary embodiments relate to an optical splitter assembly. In general, the optical splitter assembly includes a housing for an optical splitter element configured to split at least one input optical signal into a plurality of output optical signals. Exemplary embodiments may be part of various devices or systems within an optical fiber network. For example, the optical splitter assembly described herein may be part of a fiber to the premises (FTTP), also referred to as fiber to the home (FTTH), system using passive optical networks. As illustrated in FIG. 1, a FTTP system may include or otherwise be in communication with a provider's central office 20 that delivers optical signals to a plurality of subscribers through a passive optical network or PON 10. The passive optical ne...

Optical splitter assemblies are provided. An assembly may include a housing, one or more fanout elements, an optical splitter element, an input fiber and a plurality of output fibers. The input fiber extends from an input opening of the housing to the optical splitter element. The input fiber carries an input signal to the optical splitter element and the optical splitter element splits the input signal into a plurality of output signals to be carried by the plurality of output fibers. Each of the output fibers extends from the optical splitter element to beyond a plurality of output openings of the housing. Each of the fanout elements defines one or more channels for supporting the input or output fibers. The assembly may further include tubular members for further support to the fibers. The fibers extend from the openings of the housing to the optical splitter element free of any loops.
Description
BACKGROUND INFORMATION[0001]Optical splitters are used in fiber distribution hubs of fiber to the premises (“FTTP”) networks. An optical splitter device is configured to split an incoming optical signal input into 16 or 32 optical signal outputs. The outputs are connected through a fiber optic patch panel to the distribution fibers that are dropped at the individual premises of the network. Typically, the optical signal outputs are looped at least once between the optical splitter and the fiber optic patch panel. The size of the loop varies depending on the type of fiber of the optical signal outputs.[0002]An optical splitter and the optical signal outputs extending from the optical splitter are housed at least partially within a cassette or assembly, which in turn forms part of a fiber distribution hub. The overall size of the assemblies varies between vendors and is usually relatively large compared to the actual optical splitter. The variation and overall size of the assemblies m...
